Ore Genesis Of Bauxite

The mineralogy and genesis of the bauxite deposits of ...

Gibbsite, boehmite, iron oxide, kaolinite and quartz are the most abundant minerals. Field and laboratory evidence indicate that the White Limestone is the source of the ore, and by comparison with other deposits and phase equilibria work on related systems it is deduced that a volcanic ash could not be the source material.

01/07/2013  Diaspore, boehmite, kaolinite, smectite and hematite are the major mineral components in the bauxite ores with small amounts of gibbsite, illite, goethite, pyrite, anatase, zircon, quartz and feldspar. The textural features of ores suggest that the bauxite has an authigenic origin but locally underwent transportation and re-deposition.

Bauxite - Sandatlas

Bauxite is an aluminum-rich sedimentary rock. It is the principal ore of aluminum. Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite 4. The major impurities are iron oxides and hydroxides (which give reddish color to most bauxites) and clay minerals.
